GOILER-FRONT FOR CARDS.

Patented Mar. re, 1916.

Application filed January 9, 1913. Serial No. 740,971.

T 0 all whom it may concern I Be it known that I, ELwr H. Roovnv, a citizen of the United States. residing at vVhitinsville, in the State of Massachusetts, have invented certain new and useful Impro ements in Coiler-Fronts for Cards, of which the following is a specification,

The inventicn is an improved carding apparatus adapted to produceinultiple slivers condensed to such extent and with such degree of fineness and uniformity of weight as to be ready for immediate introduction to the slubber without the us al intermediate steps of drawing and doubling and without the employment of a rubbing condenser.

The objects and particular features of the improvement reside in the provisions hereinafter set forth and claimed, whereby uni-- form sliversof sufficient fineness to be immediately converted into fine hank roving, can be obtained from the fleece from a single card. which latter may run at its maximum efficiency. as may be reouired for the particular work in hand. ,Heretofore the card sli ers have'been passed directly to the roving frame only when a rubbing condenser such as the J osephy condenser has been used or where a very coarse yarn for special purposes not requiring particular uniformity in weight has been required.

To the end of obtaining the results of the Josephy condenser. as respects fineness of yarn, but without the complication and ex pense of suclimeclianism, the present invention comprises a special coiler front in combinaticn with a carding machine having its doifer cylinder suitably divided so as to deliver a plurality of separate webs or narrow fleece sections insteadof a single or double fleece as heretofore, In its most highly developed form the invention prefers eight or more of. such fieecesections from the card and the present exem'plification of the invention refers to'eiglit of such sections. The fleece sections from the cardthus divided are simultaneously, and independently condensed in two stages under conditions which arejthe same for each section and are then simultaneously and independently transferred also under equal conditions to a corresponding series of sliver cans forming part of the front and into which each condensed section of sliver is discharged and coiled. By such method of handling each of the tenuous fleece sections or slivers is preserved uniform in weight, although they have to travel different distances to their respective cans, and it thus becomes practicable to place such cans directlv behind the slubber without resort to doubling in the draw-frame.

The improvement is also concerned with the manner of construction and assemblage and the mode of operation of the several parts shown in the drawing, independently of the'number of subdivisions of the fleece, whereby the slivers are first partially condensed and then further and morecompactly condensed, as they are laidin the cans, and whereby the apparatus is rendered compact'as to its arrangement f-cans-and generally convenient of use for the purposes above stated. 7 I I The invention also. includes certain features of economy of manufacture as well as the adaptability of the front to existing cards. all as will be apparent to those skilled inthis art and as will be pointed out in the claims.

In the drawings. Figure 1 is a top plan view with parts broken out. of a dofier cylinder. of a divided card and a coiler front therefor employing this invention. Fig. 2 is a similar side elevation of the same. Fig. 3 is, a top plan of the rotary can-stands of the coiling mechanism; and Fig. 4 is a longitudinal section of the same apparatus as shown in Fig. 1, with a modified form of sliver table.

For convenience of illustration. all of the familiar mechanism of the card proper has been omitted from these figures, excepting the parts more or less directly connected with the present invention. These include clothing of the cylinder. The doffer driving I gear is marked 3 and the usual. dofler; comb is marked 4, being operated through the pulley 5 by the usual mechanism. The dofl'er comb is placed so as to co-act with the dotfer cylinder at a point which is substantially tangent tothehorizontal diameter ofthe cylinder. In such position the dirt liberated by the comb falls clear of the cylinder and not back upon it, as \vould'be'the case if located above the position indicated, and inasmuch as the present apparatus is specially useful for working waste cotton, which is usually more or less dirty, such location of the doficr comb is desirable.

The driven dofler gear 3"d'rives an adjustabletrain of gears 6'and 7, journaled on; a' gear plate 8boltedto the side frame of the" card, and from this train the delivery roll shaft 9 is driven through the gear'10, and from the same train a countershaft 1 1 isd'ri've'n through an idler '12 and a1 shaft gear 13. The roll shaft 9 extends transversely across the card frame, being journaled on the projecting ends of the latter, and carriesthe lowermostrollsl l of four pairs of calender rolls which are thus disposed parallel to the doffer comb and directly in front of it. The upper rolls 15 of these delivery rolls are'of solid metal and re's'tby gravity upon. their respective lower rolls '14, being held rot'atablv' and removably in such-positionby the confinement of their end gudgeons inthe sup'pcrts 16 as shown int hed-rawings. The series of delivery rolls is separated from-the doffer comb'by a plate orlbar 1 7 whichis secured to or against the rear sides of the supports 16, and supports a series oftrumpets 18, of which there are 7 two for each pair of rolls and one for'each section of the divided-fleece. The said sections-immediately on leaving the doffer comb,mov'e horizontally to their respective trumpets from which they are drawn by the delivery rolls, being thereby subjected to the first condensation. The delivery rolls are provided with clearers119, of a generally triangular shape, as" indicated in Fig. 4, so

that they will fit in the crotch between the rolls and the forward side of the trumpet plate 17'. Such 'clearers are desirablymade offmetal and solid so as to add weight to p the upperdelivery rolls 15 and thereby dwi'seso-arranged as to give an equal weight assist inthe drawing of the fleece through the trumpets. Since the upper rolls rest upon the two fleece sections or slivers at substantially equal distances from their ends the pressure 'imposed on each of the two slivers is substantially equal and as each pair of-rolls has the same size and w ight and is equipped with the same weightof clearer, the slivers emerging from 't herolls are thereby equally condensed. Thetapes'cn the doifer cylinder are likep'er linearunit toeach fleece section, so that tl-ie' sl'iversthatfmove from the'card to-the sliver table of the front are thus substantially identical in their physical condition.

From the delivery side of the calender rolls the slivers pass upwardly and without support to the lower-,edge of an apron 20, which is part of the sliverv table 21. This table is supported on end standards or legs 22 and overlies the set of sliver cans '23.

The apron 20 is rearwardly and downwardly inclined, toward the d0fl 'er"comb and the condensing mechanism, so" that each sliver is thus unsupported for an equal distance. 7

The sliyers are moved along the smooth surface of ,the apron and the flat surface of the table'by means of a second series of pairs of calenderro-lls by which they are further condensed and delivered into the cans.

There is one pair of such rolls assigned to each sliver'arranged above and eccentrically to the axis ofrotation of the can beneath it to which it delivers. In the preferred form;

of the invention, the eight or more sliver cansare arranged in two transverse rows of'four cans each and the table is apertured' above each can to 'let' the sliver through as wellas to accommodate and expose the calender rolls. The rolls for the sliver cans of the first row are arranged in confined removably, in brackets 27. Each upper roll is provided with a clearer 28,

which rests upon it. This clearer maybe swung back on its hinges when desired and the upper roll may be removed from its working position in the obvious manner.

The'roll shaft 25 is connected by a beveled i shaft gearing disposed beneath the table (see dottedlines in Figs. 1 and 2) with an other lower roll shaft such as 29, of. which there may be as many as there are rows of cans. In the case of a twelve-sliver machine there willbe two additional roll-shafts like 29, under thesliver table,'each'operating a transverse rowof four cans, and all driven from the first roll-shaft 25. v The shafts of thesecond, or second and third rows, may

be'and preferably are identical with the shaft 25, except for the locatirn of the lower rolls 30 thereon, which are arranged to provide a substantially straight course for each sliver. ,Fach' lower .roll supports an upper roll 31, equi ed with a holding bracket 27 and a clearer 28. y v e The set ofroll-shafts 25 and 29 i'nthe present case are driven'p'ositively and in unison with; the card, for which purpose they are" geared by means tr inclined bevel gear shaft 32,- With the transverse counter-shaft 11 above referred to. The shaft 32 is journaled at one end on thesliver table and at its lower end in a bracket 33 on the card, at which point it carries a pinion engaged by a drive pjinion on the countershaft 11. The counter-shaft also drives, through appropriate bevel gears, the upright shaft 34, which actuates the coiler mechanism. The latter is placed between the end standards or legs of the table and comprises a plurality of rotary plates or stands 35, upon which the sliver cans-are adapted to be placed and by which they are rotated when receiving the slivers The stands 35 are mounted in a suitable casing and inter-connected by the gearing, as indi cated by the dotted pitch circles, and driven from a spur gear at the foot of theishaft 34. All the cans are driven in the same direction. I

In the form of the invention shown in Fig. 4, the construction and operation throughout is the same as in the form first described and the calendar rolls 36 are disposed in the same relation on the sliver tableas the rolls Qand 26, but they are horizontal instead of one above the other and both are driven positively from the supports a trumpet 38, andmay, if desired,

form part of a usual stop motion mecha nism. The trumpets 38 point downwardly and directly into the bite of the rolls and their orifices are smaller than the orifice of the trumpet 18 on the card, so that each fleece section is condensed first only to such extent as may be necessary to enable it to be lifted to the height ofthe sliver table and then is further and finally condensed just as it enters the can. It will be understood that the can stands for this form may be the same as shown in Fig. 3.
